CE ÎNSEAMNĂ CONSTANTAN ÎN ENGLEZĂ?
constantan
Constantan este un aliaj de cupru-nichel constând, de obicei, din 55% cupru și 45% nichel. De asemenea, cunoscut sub numele de Eureka, Advance și Ferry. Principala sa caracteristică este rezistivitatea, care este constantă pe o gamă largă de temperaturi. Sunt cunoscute și alte aliaje cu coeficienți de temperatură scăzut, cum ar fi manganul.
Definiția constantan în dicționarul Engleză
Definiția constantan în dicționar este un aliaj de cupru și nichel. Are o rezistivitate ridicată care nu variază semnificativ cu temperatura și se folosește în rezistoare și, cu cupru, în termocupluri.
